Abstract (en)
1. Liquid metering unit, and in particular milk metering unit, comprising a measuring device (30) receiving the liquid from which the gas has been removed by way of an outgassing device (10), first and second valves (25, 45) actuated pneumatically to control respectively the admission of the liquid into the measuring device, and its discharge therefrom, a sensor (32) associated to the measuring device to issue a measuring signal (Sm) every time a predetermined quantity of liquid smaller than the total capacity of the measuring device has been introduced therein, and a control and counting device (70) receiving the measuring signals and controlling the first and second valves to cause the discharge of the liquid out of the measuring device every time said predetermined quantity is introduced therein, metering unit characterized in that it further comprises a device (50) for taking samples with a sampling duct (57) which is equipped with a third valve (58) and connects the outgassing device (10) with an orifice (56a) provided in the bottom of a chamber (56) into which extends the said sampling duct, and to which orifice a sample container (51) can be connected outside said chamber, and in that said first, second and third valves (25, 45, 58) are actuated by way of electrovalves (41, 43, 61) controlled by electrical signals produced by the control and counting device (70) in response to the measuring signals (Sm), the third valve (58) being controlled to open the sampling duct (57) for a predetermined period of time (T1), in response to at least one measuring signal (Sm) produced during a counting operation.
Abstract (fr)
Des vannes (25, 45) actionnées pneumatiquement commandent l'entrée dans le dispositif de mesure (30) de liquide provenant d'un dispositif de dégazage (10) et la sortie de liquide hors du dispositif de mesure. Un dispositif (50) de prélèvement d'échantillons est relié au dispositif de dégazage par une conduite de prélèvement (57) munie d'une troisième vanne (59). Un capteur fournit un signal de mesure (Sm) à chaque fois qu'une quantité prédéterminée de liquide inférieure à la capacité totale du récipient de mesure (31) a été introduite dans celui-ci, et un dispositif de commande et de comptage recoit les signaux de mesure, applique des signaux électriques à des électrovannes (41, 43, 61) commandant les vannes (25, 45, 59) pour provoquer la sortie du liquide hors du dispositif de mesure, à chaque fois que ladite quantité prédéterminée y a été introduite, et l'ouverture de la conduite de prélèvement.
